A cookie is a file containing an identifier (a string of letters and numbers) that is sent by a web server to a web browser and is stored by the browser. The information is then sent back to the server each time the browser requests a page from the server. This enables a web server to identify and track web browsers.
There are two main kinds of cookies: session cookies and persistent cookies. Session cookies are deleted from your computer when you close your browser, whereas persistent cookies remain stored on your computer until deleted, or until they reach their expiry date.
When visiting theydonbois-pc.gov.uk, we collect standard cookie information so we can track visitor behaviour patterns. We do this to monitor how users visit or how long visitors spend in different parts of the site. This helps us to improve our web site and to plan our future work.
